## piz-daint @ CSCS

Build instructions for the Piz Daint (GPU cluster).

These instructions haven't been tested recently. They are still for a version
based on distutils rather than setuptools that was dropped towards the end of
the development of this version of the benchmark suite. They are here because
it is the only still relevant set of instructions for a GPU-based machine.
